2 Claims. (Cl. 138-89) This invention relates to cleanouts, devices which provide a means of access to the inside of an underground or concealed pipe system, and in particular to a cleanout that is readily installed in the system so that the closing screw plug lies ilush with the floor. It is common in installations of cleanouts to locate them in a pit in the floor or as objectionable protruding obstructions above the floor level. These two types are troublesome because of the inconvenience of access and unsanitary and dangerous conditions when in a pit and because of the danger to people when projecting above floor level.

The object of this invention is to provide a cleanout having an adjustable feature which makes the cleanout readily installed so that the closing plug lies flush with the nished floor or roadway, thus eliminating the above objections.

The figure is a longitudinal cross section of this invention. In the drawing a sectional view is shown of the cleanout in assembled condition.

The three essential parts of this invention are shown as a sleeve 1, a female cleanout housing 3, and a plug 6. Sleeve 1 has external threads on an enlarged annular section 2 adjacent to but spaced from its upper end.

The female cleanout housing 3 has an internal thread 4 running its entire length to within a short distance of the top end of the housing. This threaded housing mates with the externally threaded annular section on sleeve 1. The top end of this housing contains a separate internal pipe thread 5 for a plug 6.

Plug 6 is a simple sealing plug in the form of a disc having external pipe threads 9 which mate with the pipe threads 5 so that when the plug is tightened the top of the disc is flush with the top of the housing. Thus the plug screws into the topmost portion of the cleanout housing to make a water-tight and gas-tight seal. The plug 6 has a conventional recessed wrench opening in its upper surface for purposes of removal and installation.

When assembled there is an annular space or internal hub 12 left between the housing 3 and the upper end 8 of sleeve 1, said space being bottomed by the top of annular section 2.

It can be seen that by using the parts of this invention as described, a cleanout can be installed flush with the floor in the following manner. Sleeve 1 is connected to the pipe system 10 in the normal manner and as conventionally illustrated in the figure so that the upper end of the sleeve extends towithin a short distance below the position to be taken by the upper surface of the door 11. The cleanout housing 3 is screwed over the upper end of sleeve 1 and is screwed down until the top of the cleanout housing comes to rest at about the established floor level. At the time when the floor is put in, the cleanout housing 3 is adjusted flush with the oor surface. After the housing has been adjusted to the correct elevation, a sealed joint 7 is formed by use of molten lead or other similar sealing materials in space 12 to form a watertight and gas-tight joint between the sleeve and housing. Plug 6 is then screwed into place to seal the system and at the same time to provide a readily accessible means for reaching the inside of the pipe system.

From the above description and sketch shown, it will be evident that various forms of the invention may be made without departing from the spirit of the invention, and as included in rn-y appended claims.

I claim:

1. An adjustable cleanout comprising a sleevehaving an enlarged annular section spaced from the upper end of said sleeve, said section having external threads, and an elongated cylindrical female housing having internal threads for a substantial portion of its length so that it may be screwed on said annular section and adjusted relative to the sleeve, said housing when screwed onto the annular section on the sleeve providing an annular space completely around the upper end of the sleeve directly above the enlarged annular section of the sleeve, said space forming a receptacle which receives calking material to seal the joint after the cleanout is adjusted, and a removable sealing means for closing the top part of said housing.

2. A cleanout as in claim 1 in which the said internal threads in the housing stop short of the upper end thereof and said upper end is internally threaded with conventional type pipe threads and the sealing means consists of a plug in the form of a disc having external pipe threads mating with the pipe threads in the housing so that the top of the disc is ush with the top of the housing.
